Introduce a new ast type, SimdLoadLane, since it takes a lane index
immediate, on top of the usual memarg, and also pops a v128 off, in
addition to the index.
The exact binary opcodes for these instructions are not yet fixed, I've
used the ones currently implement in V8 and LLVM/Binaryen, we can change
those later.
Also added a new test generation script, and the generated test files.
